Abstract

PROBLEM TO BE SOLVED: To adjust a weighty balance easily by providing a holder main body and a ring and constituting an assembly tool for assemble the ring to the holder main body separatably so as to releasably engage with the inner periphery surface of the ring and the outer periphery surface of the holder main body. SOLUTION: At the using time, at first the holder main body 20 on which a prescribed tool is mounted is mounted on the rotary shaft 12 of a machine tool and an unbalance direction and unbalance amount are measured by the rotation of the rotary shaft 12 under this state. Then, the screw member 28 is slightly loosened to such extent that the ring 22 is not rotated for the holder main body 20 by the own weight and vibration and under this state, a cover 24 is rotated for the ring 22 so that the hole 62 can release the hole 50 or 52 for balance adjusting responding to the measured unbalance direction. Then, the screw member 28 is tightened and the balance adjust is finished after arranging the balance adjust members 54, 56 responding to the measured unbalance amount to the prescribed holes 50, 52 for balance adjusting.
